Science
Mechanism of Action
This ingredient operates on multiple fronts: As a polyglyceryl ester, it effectively blends and stabilizes immiscible oil and water phases, crucial for emulsion integrity. On the skin, it forms a protective barrier that helps retain hydration, thereby preventing moisture loss and promoting a softer, smoother skin texture. Its origin from shea butter endows it with beneficial compounds like unsaturated fatty acids, Vitamin E, and allantoin, which contribute to skin regeneration and exhibit anti-inflammatory properties, potentially reducing redness and irritation.
